Low-carbon high-durability concrete carbon-reducing auxiliary agent and preparation method thereof
The invention discloses a low-carbon high-durability concrete carbon-reducing auxiliary agent and a preparation method thereof. The modified asphalt is prepared from the following raw materials in parts by weight: 20-50 parts of modified asphalt, 20-50 parts of modified metakaolin, 10-30 parts of reinforced fibers, 10-30 parts of mineral filler, 8-15 parts of a water reducing agent and 5-10 parts of an exciting agent. Through combined use of the modified asphalt and the modified metakaolin in the auxiliary agent, the mechanical property of the concrete prepared from the machine-made sand and the recycled aggregate can be remarkably enhanced, and synergistic interaction is achieved; the slump of the concrete slurry is improved through combined use with the potassium boron stone powder; and by combining with the mica mineral powder, the static compressive elastic modulus of the concrete is improved.
本发明公开了一种低碳高耐久混凝土减碳助剂及制备方法。由如下重量份数的原料制成：改性沥青20‑50份、改性偏高岭土20‑50份、增强纤维10‑30份、矿物填料10‑30份、减水剂8‑15份、激发剂5‑10份。本发明的助剂中改性沥青和改性偏高岭土的组合使用，能显著增强以机制砂和再生集料制备的混凝土的力学性能，且协同增效；以和钾硼石粉的组合使用，改善了混凝土浆料的坍落度；以和云母矿粉的组合使用，改善了混凝土的静力受压弹性模量。
